Sets the number of unique partial substructures that can be traversed
during the exhaustive
MCS search.
If this limit is reached than the exhaustive
MCS search throws a “MCS search truncated” waning and terminates returning the
maximum common substructures identified prior to reaching this limit.

Warning

Use this function with caution.
Reducing the default limit will result in terminating the exhaustive MCS searches
prematurely thereby preventing them from locating the maximum common substructure(s).
Increasing this limit can result in significantly increasing the execution time
in case of complex or large molecule pairs.
